FIGURE 2 – MAXIMUM POWER vs CASE TEMPERATURE

RH1084

The maximum Power dissipation is limited by the thermal shutdown function of the regulator chip in the VRG8684.

The graph above represents the achievable power before the chip shuts down. The line in the graph represents the

maximum power dissipation of the VRG8684 This graph is based on the maximum junction temperature of 150°C

and a thermal resistance (
